- Application filed December 9, 1910. Serial No. 596,482.

To all whom 1' t may concern Be it known that we, BENJAMIN H. BUNN- andliouanzo N Sonia, citizens of the United States, residingat Chicago, inthe county of Cook and State of Illinois, have invented certain new anduseful Improvements in Parcel-Tiers, of which the following is aspecification.

This invention relates to machines for tying parcels, bundles orpackages, and is designed to wrap a string or cord from a suitablesupply around the package, preferably in two directions, and then tiethe string tightly adjacent to the package or parcel sothat after theknot is completed the package will be securely and tightly bound. One ofthe principal uses for which our invention is intended is that of tyingpackages of letters or other mail matter, but obviously the machine isadapted for tying various kinds of packages or parcels.

Among the objects of the present invention are to provide a simple,compact and cl'licient machine for clamping a parcel, package of lettersor the like securely on a receiving plate, winding the string or cordaround the package in one direction, then turning the package so thatthe string will be wound around in another direction without looseningthe tension of the same, then knot-ting the string and severing the samewithout leaving any short pieces of string to fall from the knotter, andfinally releasing the package preparatory for the next operation.

Other special advantages, such as relate to the details'of constructionand arrangement of parts. and particularly to the knotting mechanism,will be more particularly pointed out and described in the followingspecification.

\Ve have illustrated our invention in the accompanying drawings, in wiich- Figure 1 is a front elevation of the machine, parts being omitted,broken away, or

shown diagrammatically for convenience in illustration; Fig. 2 is anenlarged end view taken from the right-hand side of Fig. 1, parts inthis view also being broken away for convenience in illustration; Figs.3, 4, 5, (i and 7 are details of portions of the package orparcel-clamping or compressing devices and cam for operating the same;Fig. 8 is an enlarged detail of one of the package-clamping devices,also showing a portion of the mechanism for turning the pack agereceiver; Fig. 9 is a side view of the mechanism shown in Fig. 8; Figs.10 and 11 are details of one of the string-guiding devices; Fig. 12 is adiagrammatical view illustrating the knotting operation; Fig. 13

As illustrated in these drawings, indicates a substantial frame havingbearings for a main driving shaft 31, which shaft may be turned by meansof a crank 32 or by means of any suitable form of power, such forinstance as an electric motor, which, however, is not shown. A segmentalgear 33 is mounted on the shaft 31, the toothed portion of this gearbeing adapted to mesh with the teeth of a pinion 34 mounted on a sleeve35, which sleeve is rotatably supported on a stub shaft 36 extendinginwardly from one end of the frame. The gear 33 contains approximatelyor exactly twice the number of teeth as the pinion 34, so that with eachrevolution of the main shaft the pinion and sleeve will make twocomplete revolutions. In order to prevent lost motion of the pinion andsleeve and to hold the same in fixed position during the time the blankportion of the gear 33 is passing the pinion 34 and also to insure theproper meshing of the teeth, the pinion is provided with two rollers 37,37, which engage with a curved plate or segment 38 on the side of thegear 33, and on account of such engagement, hold the pinion in fixedposition with respect to the gear. Securely mounted on the sleeve is acord or twine holder 39 of any ordinary or preferred form ofconstruction and also a guide arm 40 for guiding the string or cord 41.The stub shaft or pin 36 carries at its inner end a plate 42, which,together with a plate 43 extending inwardly from the opposite end of theframe, forms a table, as it were, for the top ,of the machine where thearticles to be tied are placed. A space is left between these plates 42and 43 for the passage of the string or cord during the tying operation.

The parcel, bundle of letters or other article to be tied is placed uponthe combined uide and holder 44. This holder referalfly comprises abottom plate 45, havmg upwardly extending sides or abutments 46 and 47extending along two sides thereof and forming, as it were, an open-sidedbox. The plate 45 is mounted on a vertical shaft or pivot 48, working ina sultable bearing on the plate 43. At the lower end of the shaft 48 isa crank arm 49 which 15 connected by means of a link 50, with the upperend of a bent lever 51, which lever is pivotally mounted at 52 onprojections 53 ex- I be wound around the package or parcel in two 7directions, and it is also preferably formed so as to give a slightmovement to the holder just at the completion of the tying operation inorder to assist in properly forming and releasing the knot.

The parcel to be tied is clamped or compressed by what may be termedrelatively continuous and intermittent clamping devices. One of thesedevices, which is best shown in Figs. 8 and 9, consists of a plunger-57which is adapted to reciprocate in a bearing 58 connected to the top ofthe plate or abutment 46, this plunger being arranged at one side of thepivotal support of the holder 44. The plunger is held in normally raisedposition by means of a spring 59 but may be held in depressed engagingposition by means of a pawl 60 which coacts with a toothed rack 61 onthe side of the plunger. This plunger is pressed downwardly to engagewith the parcel by means of a tappet 62 which engages with the head orenlarged lower end of the plunger, as clearly shown in Fig. 1. Thetappet 62 projects from a yoke 63, which yoke with its operative partscomprises the intermittent parcel clamping mechanism. The sides of theyoke extend downwardly through bearings 64 in the plate 43, and theirlower ends are connected by means of a bar or rod 65 shown in Fig. 5. Arod 66 is pivotally connected at 67 to the center of the bar 65 and hasits opposite end slidably engaging or telescoping with .an arm 68, whicharm is pivotally connected at 69 to a second arm 70, the latter beingpivoted at 71 to a vertical post 72 extending upwardly from the bottomof the frame 30. The arm 68 extends some distance beyond the pivot 69,and its end is adapted to engage with a portion of the arm 7 0, therebyforming a jackknife joint which may be bent in one direction but not inthe other. At the opposite end of the arm is a roller 73 which engageswith a cam slot 74 formed in the face of a cam 75 which for convenienceis arranged on the side of the gear wheel 33. The form of the cam isclearly shown in Fig. 7. A bar 76 is pivoted at 77 to the arm 70, andits opposite end is provided with a hole fitting over a rod 78 pivotallyconnected at 79 to the arm 68. A spring 80 on the outer end of the rod78 tends to hold the bar 76 close against the lower side of the arm 70.In other words, this bar and spring arrangement tends to hold the arms68 and 70 in alinement; however, when there is a sufiicient resistanceto the downward movement of the yoke 63, this double arm willyield orbend as clearly indicated in Fig. 6, the inner end of the arm 68pressing down against the bar 76, which actlon is resisted by the spring80. The cam groove 74 is so formed that during one revolution of themain shaft and at the proper times it will cause the yoke 63 to be drawndownwardly, the resistance of the parcel thereunder being opposed by thetension of the spring 80. During the first downward movement of theyoke, the tappet- 62 engages with the plunger 57 and presses a 4 of thecam and levers above desciubed, and i I again moves downwardly to engagewit-hthe parcel while the string or cord is being passed around theparcel the second time, but at this time the plunger 57 is swung aroundso that it is not engaged by the tappet. After the knot has been tied,the yoke 63 again moves upwardly to release the package, and in order toalso release the plunger 57 which is still holding the package, the yokeis provided with a second tappet 81 which strikes against a finger 82secured to .a vertically movable rod 83 mounted on the plate 46, asshown particularly in Fig. 8. This rod is normally held in de pressedposition by means of a spring 84, and has its upper end in alinementwith the outer end of the pawl 60 so that when the rod is raised theupper end strikes the pawl, thereby releasing the same and allow- At thetime the mal position, and this swinging movement tends to throw thebundle toward the side of the machine and the completed bundle or parcelpasses down over the downwardly bent end of the plate 42 and a secondguide plate 85, as shown in Figs. 1 and 2.

Besides the means for holding and turning the package, the machine isprovided with novel mechanism for holding, guiding, knotting andsupporting the string or cord, which devices or apparatus will now bedescribed.

In starting the knotting operation, the free end of the string or cord41 is caught in the cord holder 86, which holder is operativelyassociated with a guide or push oif member 87 The holder 86 is mountedon the end of a pin 88, which pin extends through a hole 89 in a casingor block 90 secured to the lower face of the plate 43, as best shown inFigs. 20 and 21. The outwardly extending end of the rod 88, which isshown bent in this instance for the purpose of clearing other parts ofthe machine, is

provided with a spring 91, tending to hold the rod in retractedposition, that is, so that the holder or head 86 presses tightly againstthe outer face or wall of the block or casing 90, the string being heldbetween this head or holder and the face of the wall. I1nmediately belowthe hole 89 is a second hole 92- passing through the casing 90, throughwhich passes a bar or rod 93, the outer end of which carries the guideor push-off member 87. The bar or rod 93 is provided with.

the parcel, when the arm 40 is swinging around the parcel. As the stringis not to be, held for tying until after ithas passed around the parcelthe second time, it will be noted that it must be guided or pushed awayfrom the holder during the first revolution of the arm. and this is thepurpose of the guide 87 It will also be noted that the cord holdershould be released at about the time the knot is completed and justbefore the cord is severed, in order to free the short portion of thecord between the holder and the knot. This is accomplished'by giving thebar 93 two distinct forward movements. During the first movement, asindicated in dotted lines, the guide 87 moves forward a short distanceso as to throw the cord away from the holder; then, just at about thecompletion of the tying action, the bar 93 again I moves forward agreater distance, which causes the pawl 94 to strike against the arm 95,throwing the arm away therefrom and causing this arm to press againstthe roller 97, thereby pushing the holder forward reciprocating bar orslide 100 is provided with laterally extending lugs or projections 102,which engage with the upper end of a lever 103 which 1s preferablypivoted on the same shaft 52 WhlCll carries the lever 51. The lower endof the lever 103 is provided with a roller 104, which engages with aslot 105 preferably formed in the cam wheel 56, this slot being giventhe proper configuration in order to produce the desired move ments ofthe slide or bar 100. The slide 100,

which is mounted in the second slide 101 which supports the knottermechanism, is provided on one side of the knotter with a cutting-0dknife 106 and a string pusher 107. Pivoted to the slide 100 on theopposite side of the knotter is a stripper 108,

which is adapted to help complete the knot and to strip the completedknot from the jaws of the knotter by pushing the loop of twine which iswound about the knotter back toward the package while the cut ofi endsare firmly held by the teeth on the lower jaw well back between theclosed jaws, thus tightening the string and insuring a firmly boundpackage. The forward end of this stripper is normally held away fro-mthe knotter jaws by means of a spring 109, and in order to cause theforward end to come in close to the knotter jaws at the proper time, theother end of the lever isadapted to engage a cam or shoulder 110 on theslide 101 as the latter moves forwardly.

In tying parcels which have comparatively little resiliency, such forinstance as a package of letters, it is desirable, not only thatthestring be wound sufiiciently tight around the package, but that the knotbe made as close as possible thereto, so that after the knot has beenformed the tension of the string around the package will not besubstantially lessened on account of the length of the string betweenthe knotter and the adjacent portion of the package. In order toaccomplish this result, we have provided a novel form of knotter andmeans for operating the same, as well as novel devices for guiding ordrawing the two plies of the string into proper position to be engagedby the knotter. The knotter 111 is mounted in the end of the slide 101,as clearly indicated in Figs, 18 and 19. The main jaw 112 of the knotteris mounted at the upper end of a short shaft 113 which has its bearingin the front end of the slide 101. The

lower end of the shaft 113 is provided with a bevel gear 114 whichmeshes with a corresponding gear 115 on the end of a short horizontalshaft 116 which also has its bearing in the slide 101 and carries at theopposite end a pinion 117. This p1n1on is turned at the proper time forrevolving the knotter v by means of a segmental gear 118 extending froma disk or plate119 mounted on the main shaft 31. The teeth of thissegmental gear are preferably made of short pins, as indicated in Figs.2 and 14. The lower or movable jaw 120 of the knotter is pivoted at 121to the main jaw and carries at its lower end a roller 122, which rolleris adapted to engage with the cam surface 123 at the end of the bearingfor the shaft 113, whereby the lower end of the jaw will be swungoutwardly at the proper time in order to cause the'jaws to open toreceive the string or cord. The portions of these jaws which engage withthe string are comparatively long and narrow, as clearly indicated inFigs. 15 to 19, inclusive, and also Figs. 22' to 25, inclusive. Thelower jaw 120 is also preferably provided with a number of teeth 124, asindicated particularly in Fig.

24. The upper jaw 112 is preferably flattened' as indicated at 125, Fig.23, in order to form a guide or surface for the end of the stripper 108to slide along when this stri per assisting in completing the formationof the knot. After the jaws have been opened to receive the string, theyare again closed by means of an arm 126 which is pivoted at 127 to theslide 101 and is held in normal position by means of a spring 128, thearrangement being such that when the roller 122 engages with the end ofthis arm, it will be pressed inwardly, thereby causing the jaws toclose. As it ,is necessary for these jaws to hold the string-withconsiderable force at the completion of the knotting operation, we havearranged the end of the arm 126 so that it will strike a cam surface 129on a portion of the slide 100 when the knotter recedes to complete theknot-ting operation. This cam surface presses against the arm 126 andthereby helps to hold it in close engagement with the roller 122 butreleases the arm before the endof the stroke to allow the ends of thestring to be drawn out of the knotter. The slide 101 is reciprocatedhorizontally by means of a lever 130, the upper end of which engageswith lugs 131 on the side of the slide. This lever is pivoted at 52 onthe same shaft as the levers 103, and 51 and is provided at its lowerend with a roller 132- fitting in a cam slot 133 in the cam wheel 56,this slot being so shaped as to give the proper timing and movement tothe knotter. In order that the knotter may properly engage with thestring at a point close to the package, we prefer to mount the slide 101in such manner that its outer end, that .pressed downwardly against theslide by means of a spring 137. The back or rear slot 134 is justsufliciently wide to allow' the front end of the slide 101 to move upand down without binding at this point. In order to raise the front endof the slide at the proper time, it is provided with a roller 138 whichis adapted to be engaged by means of a cam 139 which is mounted with thesegmental gear 118 on the disk 119.

The guide which raises the lower ply 0f the string up into position tobe engaged by the knotter, comprises a bent arm or finger 140 which hasa groove 141 in its outer end for receiving the string and at theopposite end is made substantially in the form of a bellcrank. Thislever is pivoted at 142 to lugs or projections 143 extending downwardlyfrom the plate 43, and is operated by means of a pitma-n rod or link 144which is pivoted at 145 to the elbow or bend in the finger 140 and ispivoted at 146 to the slide 101. When in normal position, this finger orguide hangs down substantially as indicated in Fig, 14, but when theslide 101 moves forwardly the link 144swings the outer end of the fingerup to engage with the string and raise it into proper position,substantially as indicated by the dotted lines in Fig. 19. The nextstring guide or controlling device is the one which presses down and menthe upper ply of the string, that is the one reaching from the holder tothe top of the arcel just before the knotter is actuated. his device isbest seen in Figs. 10 and 11, and comprises a finger or lever 147havinga notch 148 in the end thereof to engage with the string, andbeing pivoted at 149 to the end of a slide 150,

which slide is mounted onthe lower side of the plate 43 at substantiallyright angles to the slides 100 and 101. This slide is provided with twoslots 151 and 152, the former of which is preferably curved at one endin order to give a desired outward movement to the finger 147, while thelatter is-preferably straight. This guide is held in position by meansof pins 153 and 154 passing through said slides and having plates 155and 156 at the lower ends thereof which bear against the lower surfaceof the slide 150. One end of the finger or lever 147 is rovided with aroller 157 which is adapte to strike against a cam-like projectlon 158on the plate 155 when the slide reaches the end of its throw, in orderto force the outer or string engagin end of the finger downwardly. Thesli e 150 is held in normal position, which is indicated by dotted linesin Figs. 10 and 11, by means of a sprin 159 which connects between adownward y projecting lug on the slide and a pin on the plate 156. Thisslide is also provided with a downwardly projecting arm 160 having aroller 161 at the lower end thereof, which roller is adapted to beenga'ged by means of a cam 162which is secured to, or projects from thedisk 119 on the main shaft 31, the arrangement being such that when thisdisk turned in the direction indicated by the arrow in Fig. 2, the camwill strike against the roller 161 as indicated in Fig. 10 and move theroller to the right, as indicated in this figure. This will cause theslide 150 also to move to the right, the first movement of the slidecausing the finger 147 to move out into the pathway of the string onaccount of the curve in the slot 151, and the continued movement causingthis finger to move to the right and draw the string down to a certainextent, while the final movement causes the roller 157 to strike the cam158,.thereby causing the outer end of the finger to move down stillfarther in order to bring the string into exact position to be engagedby the knotter.

The operation of the machine as a whole is as follows: The operatorplaces the parcel to bextied, for instance a package of letters 163, asindicated in Fig. 12, in the holder 44, the parcel at such timepreferably extending about halfway out of the holder and across thespace between theplates 42 and 43, as indicated in Fig. 1. The machine,then being started with the main shaft turning in the directionindicated by the arrow in Fig. 2, first causes the yoke 63 to be drawndown against the package or parcel, which yoke simultaneously pulls downthe plunger or holder 57. In the meantime, the free end of the string,having been caught in the holder 86, and the arm 40 revolving in ananti-clockwise movement around the package, causes the portion of thestring between the end of the arm and the holder to be wound around thepackage, tension being placed on the string in the holder 39 if desired,such tension device, however, notbeing shown. When the end of the armftO approaches the string holder 86 during lts first revolution, theguide or push-oil device 87 will move forwardly so as to direct thestring out of the path of the holder so that the string will be free tobe wound around the package a second time. At about the time the armpasses the cord holder this time and as the string is completing itsfirst winding about the package, the yoke 63 starts to move upwardly,thereby releasing the package, although it is still held to a certainextent by the plunger 57 which resevering operation takes place.*element to step forward is the guide finger mains tightly pressedthereagainst. The

next operation of the machine is to turn the holder 44 substantiallyninety degrees through the instrumentalities above described, whichcauses the package to swing around, thereby crossing'the stringunderneath the same, then the yoke 63 againmoves downwardly and pressestightly against the package or parcel until the knotter has operated.Simultaneously, thearm 40 has continued its movement around the proachesthe string holder 86, the guide 87 remains in retracted position so asto allow thestring to engage with the holder as indicated by the dottedlines in Fig. 13. Then, as the arm 40 continues to swing around to itsfirst or normal position, the k'notting and The first 147 which movesout into the path of the 'upper ply of the string, that is the portionextending between the top of the package and the string holder, thenmoves horizontally back so as to bend this portion of the string 1nto aloop, as it'were, adjacent to the lower corner of the package, asindicated in Fig. 13, thus tightening the string around the package; andat the final downward movement of the outer end of this finger,

caused by its roller striking on the cam 158, the upper ply of thestring is pressed down against the lower ply and the latter is alsoslightly depressed. Just as this occurs, the knotter moves forward sothat both jaws pass above the strings. Then the finger 117 is releasedand jumps back to its normal position, and the' finger 140 movesupwardly and engages with the lower ply of the string at the side of theknotter next to the package and slightly raises this portion of thestring so that when the knotter turns, the beak or double jaws will passunder the end of the finger and also under or behind both plies of thestring which then extend between the knotter and the package. At thistime the beveled or cam surface 125 of the upper jaw presses against thelower side of the tinger so as to raise the finger and yet remain asclose thereto as possible. As the knottcr continues to rotate, the jawsopen and engage with the two plies of string then extending between theknotter and the string holder, the string at such time beingsubstantially in the position around the knotter shown in Fig. 15. Atabout this time the string holder moves forward a slight amount in orderto release the end of the string, this end being pushed out. of theholder by means of the pusher 107, which moves slightly in advance ofthe knife 106. As soon as the end of the string is released, the holderholder and the knotter.

again recedes in order to hold the portion of the string then extendingfrom the holder to the arm 40. As soon as the holder engages thisportion of the string, the knife 106 moves forwardly and severs theremainin g ply of string then extending between the At about thistimethe knotter starts to recede and the stripper 108 moves forwardly asclearly indicated in Figs. 15, 16 and 17, the stripper serving. to pushthe loop off from around the jaws of the knotter while the jaws stillhold the ends of the string, thereby drawing portions of these endsthrough the loop around the jaws, these portions forming, as it were,double lOOps at one side of the loop around the jaws, and the latterbeing drawn .very tightly, causes a secure knotto be made. As the knotis finally completed, the holder ll swings around to its normalposition, and the plunger 57, being released, permits the tied parcel tobe thrown toward the side of the machine and over the guide plates 42and 85, and the machine is then ready to receive the next parcel orackage.

We have found y actual operation that a machine made in accordance withour invention as above described and as shown in the drawings willoperate effectively and efliciently to tie packages, for instance, ofletters or other articles and will perform such tying operation withgreat. rapidity. However, it is obvious that various changes may be madein the construction of a machine embodying our invention, withoutdeparting from the spirit thereof, and therefore we do not wish to belimited to the exact construction or arrangement of parts herein shownand described, except as specified in the appended claims, and
